ROBERT B. BANISTER, OF PROVIDENCE, RHODE ISLAND.

BUTTON-FASTENER.

SPECIFICATION lforming part of Letters Patent No. 236,973, dated January 25, 1881.

Application filed August 14, 1880.

To all whom @It may concern:

Be it known that I, ROBERT B. BANIstrEE, of Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Button-Fasteners, which improvement is fully set forth in the following specification, reference being had to the accompanying drawings, in Which- Figure 1 is a perspective View of my invention; Fig. 2, a partial sectional view. Fig. 3 represents a flat spring-blank before being formed to the shape required; Fig. 4, an enlarged sectional view of the spring after being formed. Fig. 5 is a partial transverse section of a button, a, provided with an eye, d, in the center. y

Any common button with an eye of suitable size may be used in connection with my device.

Near each end of the springcthere are formed slight projections h h. The spring is bent into a shape something like the letter U, as seen in Fig. 4, bringing the ends near together, with the projections h h insideand nearly touching each other. The middle or bottom of the spring (Model.)

is rigidly secured to the center of a back disk, (shown at 11,) leaving the ends of the spring it' free.

To attach my device to the button the eye d is placed between the ends of the spring and against the projections IL h. Then, by pressing the back disk and button together, the ends of the spring are forced over the eye of the button, which receives the projections h on each side, and the attachment is completed by the reaction of the spring. The parts are easily detached by forcing them apart.

I claimy In an improved button-fastener, the spring c, shaped substantially as shown, rigidly secured to the back disk, b, provided at its outer free ends with inner projections, h h, and adapted to be forced over the eye of a button, a, all substantially as set forth.
